Forces Energy Motion

F~(m1 x m2)/d squared Newtons Law of Gravition
An object will continue doing the same thing unless acted upon by another force 1st Law of Motion
Accerlation = force divided by mass a=f/m 2nd Law of Motion
Every Action has an equal and opposite reaction 3rd Law of Motion
Object that is projected by some means and continues in motion by it's own interia Projectile Motion
A projectile moving fast enough to continuously orbit earth Satellite
Mercury, Venus, Earth, Mars Inner Planets
Jupiter, Saturn, Uranus, Neptune, Pluto Outer Planets
A giant cometary sphere completely surrounding the solar system Oort Cloud
What is an electrical force? Positive and Negative Paricles attracting each other
What is the conservation of charge? Charge is never created or destroyed
What is an Ion? Charged Atom
F=K q1 q2/d squared Coloumbs Law
1 C equals 6.25 billion billion electrons
Ends of an electrical conductor are at different electric potentials, and charges flow from higher to lower potential. Potential difference
Ampheres Rate of electric flow of 1 coloumb per second
Ohms Electrical Resistance measurement
Current= voltage/resistance OR Ampheres = volts/ohms OR I=V/R Ohns Law
Resistors Regulate the current inside electrical devices, in ohms
Power The rate at which work is done
Potential Energy (PE) stored energy with the potential to do work
Examples of Chemical Potential Energy Batteiries, Fossil Fuels
Example of Potential Energy Bow and Arrow
Example of Gravitational Potential Energy Water in reservoir
Which car has more KE, car A or car B with twice as much mass? Car B
KE= 1/2 mass X speed OR 1/2mv squared
What composes the nucleus of an atom? Protons and Electrons
